Description: The Eye Movement Simulator is a realistic 3D mobile app that simulates the movement of extraocular muscles (EOMs) and pupillary responses. The mobile app simulates the physical examination of EOMs and pathologies can be reproduced in the simulator by using simple checkboxes to activate or deactivate the individual extraocular muscles and cranial nerves that control them. The realistic rendering in 3D provides pupillary responses, as well as blinking by the eyelids.
